Misreading the road or losing concentration doesn't create the same amount of risk on every road. It follows, logically, that the road and its surroundings are related to safety. I am still unsure how you can insist the road has no part to play in risk. If it did then all roads would produce similar casualties proportionate to their use.

Misreading the safe speed may well be the issue but the capacity for such mistakes is greater on some roads than others.
Of course we could raise the level of competence needed to gain a licence to compensate for roads which are a particular problem. Or we could re-engineer the road, change sigange or introduce prohibitions such as DWLs, stopping restrictions and speed limits.
Bearing in mind most people aren't obsessed with their driving standards, would oppose significant increases in the level of competence needed to be shown before being licensed to drive, and do make mistakes it follows that people would prefer 'dangerous' roads to be made more safe.
There is no one right answer: it is achieving a balance between the level of competence required to be granted a licence to drive coupled with reasonable expectations of how much attention people will pay to the driving task subsequently and roads that are appropriate to these facts.
